Implementation of geographical location based routing protocols in vehicular environment

摘要

Abstract An important special class of mobile ad hoc networks in vehicular environment is VANET where vehicles communicate among each other and road side units. Since road structures are predefined and vehicles move with very high speed, the connectivity among vehicles breaks very often, therefore routing becomes a very challenge issue in VANET. Most of the authors used IEEE802.11b/g based routing protocols. The standard used for VANET is IEEE802.11p. This paper implements the IEEE802.11p based two geographical routing protocols location-aided-routing (LAR) protocol and zone-routing-protocol (ZRP) for city as well as highway vehicular environment. Vehicular movement traces are obtained with VanetMobiSim tool having intelligent driver model (IDM). IDM with intersection management and IDM with lane-changing modules are used. Packet delivery ratio, throughput, delay, normalized routing load and lost packet ratio metrics are used to evaluate LAR and ZRP routing protocols implemented in VANET.
